c
c     o Get the climatogy fields for the current time step. The switches
c       for the inclusion of the individual forcing components have to
c       be set in EXF_OPTIONS.h .
c
c       A note on surface fluxes:
c
c       The MITgcmUV's vertical coordinate z is positive upward.
c       This implies that a positive flux is out of the ocean
c       model. However, the wind stress forcing is not treated
c       this way. A positive zonal wind stress accelerates the
c       model ocean towards the east.
